What is the term for the measurement of wind speed?

The term for the measurement of wind speed is an anemometer. An anemometer is specifically designed to gauge how fast wind is blowing, providing critical data for weather forecasting and aviation operations. It often consists of rotating cups or blades that spin in response to wind flow, translating the movement into a quantifiable speed measurement, typically expressed in miles per hour or meters per second.

In contrast, a barometer measures atmospheric pressure, which is essential for predicting weather patterns but does not provide information about wind speed. A thermometer is used to measure temperature, and a hydrometer measures the specific gravity or density of liquids, neither of which pertain to wind measurements. Understanding these terms and their specific functions helps clarify the distinction between different meteorological instruments and enhances knowledge of weather-related concepts.
